Project description:We tried to find the target genes of miR-100 in MGC-803 and SK-BR-3 cells, thus we uesd specific miR-100 inhibitor to knock down the level of miR-100 in the cells, with this condition, we used this mRNA microarray to find the genes whose amount changed. and they may be the target genes that miR-100 mediated. Total of four chips, MGC-AMO, MGC-NC, SK-AMO, SK-NC. MGC and SK represents MGC-803 and SK-BR-3 cells respectively. AMO is the specific miR-100 inhibitor and NC is negative control.

MGC-803 Cells: Control vs. MGC-803 Cells MYBL2 Overexpressed

Project description:MYB proto-oncogene like 2 (MYBL2) has been reported to be involved in the occurrence and development of various tumors, however, its role in gastric cancer (GC) remains elusive. In this study, the effects of MYBL2 on gene transcription and protein expression were analyzed by RNA sequencing and Western blot assays, respectively.

Gene expression profile analysis of ENO1 knockdown in gastric cancer cell line MGC-803.

Project description:Gastric cancer (GC) is the third leading cause of cancer-associated mortality. In a previous study, we identified that α-enolase (ENO1) promoted cell migration in GC, but the underlying molecular mechanisms remain to be fully elucidated. In the present study, small interfering RNAs were identified to interfere with ENO1 expression. The cDNA expression profiling was performed using an Affymetrix mRNA array platform to identify genes that may be associated with ENO1 in human GC cell line MGC-803. The differentially expressed genes (DEGs) were identified using the reverse transcription-quantitative polymerase chain reaction, followed by a series of bioinformatic analyses. As a result, there were 448 DEGs, among which 183 (40.85%) were downregulated. The most significant functional terms for the DEGs were the nuclear lumen for cell components (P=2.83×10-4), transcription for biological processes (P=3.7×10-7) and transcription factor activity for molecular functions (P=1.16×104). In total, six significant pathways were enriched, including the most common cancer-associated forkhead box O signaling pathway (P=0.0077), microRNAs in cancer (P=0.0183) and the cAMP signaling pathway (P=0.0415). Furthermore, a network analysis identified three hub genes (HUWE1, PPP1CB and HSPA4), which were all involved in tumor metastasis. Taken together, the DEGs, significant pathways and hub genes identified in the present study shed some light on the molecular mechanisms of ENO1 involved in the pathogenesis of GC.
